[protext] ProTeXt translated to spanish

[Karl Berry]

    I translated ProTeXt to spanish. 

Thank you very much!  I've put this into http://tug.org/protext/Install.

    ProTeXt is fantastic. 

And thanks for the kind words.  Thomas Feuerstack did all the real work,
I know he'll be pleased to know it's been useful.  (I think he's en
route to EuroTeX at the moment ...)

Best regards,
karl
